Abstract： Objective To study the serum level of carbohydrate antigen 125 (CA125) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and its relation with pulmonary hypertension. Methods Forty-six patients with AECOPD complicated by pulmonary hypertension, 46 with AECOPD and 38 healthy control subjects were examined for their clinical data, pulmonary function, echocardiographic findings, and serum levels of lung tumor markers and brain natriuretic peptide (BNP). Results Compared with the healthy control group, COPD patients with or without pulmonary hypertension showed significantly decreased pulmonary function (P<0.05), especially in those with AECOPD and concurrent pulmonary hypertension (P<0.05). Serum CA125 level was obviously higher in AECOPD group than in the healthy control group, and further increased in AECOPD patients with pulmonary hypertension (P<0.05). The levels of lung tumor markers (CEA, NSE, CYFRA and PROGRP) were similar among the 3 groups (P>0.05). The serum level of BNP in patients with AECOPD and concurrent pulmonary hypertension was significantly higher than that in patients with AECOPD (P<0.05). Pearson linear correlation analysis showed that serum CA125 was positively correlated with pulmonary artery systolic pressure and BNP in AECOPD patients with pulmonary hypertension (P<0.01). Conclusion Serum CA125 may serve as a serologicalindextoidentifyAECOPDpatientswithpulmonaryhypertension.
